Specification of Letters Patent. Pat t d J l 27 920 App lication filedDecember 9.191s, Serial No. 265,893.

To all w/wm'z't mayv concern:

Be it known that I, CHARLES KUDERER, a

citizen of the United States, residing at f Pittsburgh, in the county ofAllegheny and State of Pennsylvania, haveinvented new and, usefulImprovements in Motorcycle- Backrests, of which the following isa speci-1 fication.

This invention relates to a motorcycle backrest whereby the back of arider will be supported and has for its primary object to provide animprovement over that form of my invention illustrated in my copendingapplication, filed August 5th, 1918, Serial Number 248,440.

An object of the invention is to provide means for automatically movingthe supporting element to operative or inoperative I position and toglve resiliency to the supporters.

Besides the above my invention is (118- tinguishedin the manner ofsupporting and associating the elements so that the supporters may havea-pluralityof movements in all directions for obvious reasons.

With these and'other objects in view the invention will be betterunderstood from the following detailed description taken in con;-

nection with the accompanying drawing wherein: V

Figure 1 isa vertical sectional view through one of the supportingdevices, the

. other not shown as it is of identical construction with the-one.illustrated.

Fig. 2 is a diagrammaticview illustrating. three positions thatthesupporter may assume.

Fig. 3 is an elevation of the device;

Figs. 4 and..5. are views of anarm for holding the supporter in aninoperatlve position, that is to say the dotted horizontal positionshown inFig.v2. v

Again referring to the drawing the numeral 1 designates a vehicle seatof a motorcycle. To the seat 1 is connected a rodp2 which may be of aconstruction illustrated in the above mentioned application. This rod 2has fixed thereto a'cam plate 3 having a cam surface 3. Rotatablymounted on therod 2 adjacent the plate 3 is a bracket 4 having a slot 5slidably receiving a supporter 6. Hinged'toa projection 7 of the bracket4 is 'a link 81also having a yieldable connection with the bracket bymeans of springs 9. Thus it will be seen that the link 8 is drawn towardthe bracket 4 and Fig] 2.

Thus it will be seen thatthe supporter 6 is adjustably and resilientlyassociated with the bracket by means of the link 8 and springs 9.

Leaf, springs 12 and 13 areprovided con- ,nected to the link 8 andcontinuously hearing against the supporter 6 in a manner that the formerwill detachably hold a notch 11 associated with the pin while the latterwill move the supporter, 6 toward the body of the rider. I

Slidably supported by the bracket 4 between the cam plate and supporter6 is a pin 14 one end of which, is arranged to be engaged and moved bythe cam surface 4 While the other end bears against the supporter 6 formoving the same laterally against the action of the spring 13 until thesupporter assumes practically a position at right angles to the adjacentsurface of the bracket 4"so thatthe supporter 6 will lie substantiallyparallel to the rear wheel of the motorcycle when thrown to an inopera-1 tive horizontal position asv illustrated in I \Vhen in thisposition'the supporter 6 is received by a hook 16 carriedby an arm 15extending rearwardly from plate 3 and is 'held' in the hook by a spring'16. From the foregoing description takenin connection with theaccompanying drawing it should be apparent that I provide a device thatmay be thrown to a number of inoperative positions as illustrated inFig. 2 and which will have the proper resiliency when associated withthe arm pits of a rider and besides the supporters will be given thenecessary lateral movements so as to be properly positioned withrelation to the rear wheel of .a motorcycle. 1

It is oficourse to be understood that the parts may'be constructed andassociated in other manners than shown such as changing the constructionfor accomplishing a cam action between the supporter 6 and rod 2 r andthe yieldable manner of connecting the supporter 6 to bracket 4'therefore, I do not desire to be limited in anymanner except as setforth in the claims hereunto appended.

Having described my. invention, what I' claim is:

1. In a device of the character described,

' a fixed member, a bracket movable about the same, a supporting memberrockably connected to the bracket, and cooperatlng means carried by saidfixed member and the bracket for moving said supporting member into apredetermined position about its axis of rocking movement and holding itin this position when the bracket is turned into a predeterminedposition about the fixed member.

2.In a device of the character described, a fixed rod, a cam membersecured to said rod, a bracket loosely mounted on said rod,

In a device of the character described,

a fixed rod, a plate secured on the rod and provided with a cam element,a bracket loosely mounted on the rod adjacent the cam face of. saidplate, a supporting member rockably mounted in the bracket for movement'toward and away from the rod, and a pin slidable in the'bracket with oneend in contact with'the plateand its other end adjacent the supportingmember whereby cam element. 5. In a device of the character described,

by turning the bracket about the rod thepin will be forced inwardly ofthe'bracket by said cam element so as to move the supporting member intopredetermined position in the bracket and hold it in this position.

7 4. In a device of the character described,

a fixed rod, a plate secured on said rod and provided on its outer'facewith a cam element, a bracketloosely mounted on the rod adjacent theouter face of the plate, a supporting member pivotally connected to saidbracket for rocking movement towardand away from the rod, and a pinslidable through the bracket of such length and so positioned as tocontact with the supporting member above the pivot thereof so as to rocksaid member outwardly in thebracket and:

hold it in thiszposition when said bracket is turned about the rod so asto cause the:

inner end of the'pin toeontact with said a fixedrod, a plate secured onsaid rod, a bracket loose on the rod adjacent said plate,

. a supporting member rockably mounted in thebraeket, an arm extendinghorizontally from the plate and provided with a member for receiving andsupporting the outer end portion of said supporting memberiwhen rockedinto substantial horizontal position,

and cooperating means carried by said'plate V and the bracket for movingthe supporting member into position to engage into the receiving andsupporting means of said arm when the bracket is turned about the rod soas-to'move the supporting member into parallelism with and adjacent thearm.

, 6. In a device of the character describech'j a fixed rod, a platesecured thereon and having a camelement on itsouter face, a bracketloose on the rod, a supporting member extending through the bracket andcoi'inected" thereto for movement-towardandaway from V the rod, anda-pin slidablein the bracket? with one'end inc'ontact withthe camiacefofthe plate, said pin being of suchi'len'gtli' and so positioned as 'tocontact withthesufpport ing' member so as to force the same out wardlywhen the pin is forced inwardly of the bracket by contact with said camele- "ment,'the camielement beingpositioned'for contact with the pinwhen the bracket is turned into substantial horizontal position. 7.adevice of the character described,

V .c 8. Ina device of the character described,

' force the-locking pin into the bracket when 1 a fixed rod, a cam platefixed thereto, a

bracket rotatably mounted on therocbadj acent the cam plate,-a linkpivoted to the bracket, a supporter slidably mounted in the. bracket and'adjustably'connected tothe link, elements yieldably connecting the linkto the bracket and a pin slidably mountedinthe V bracket and arranged"to enga-ge'rthe cam plate and the supporter for moving the lat ter in apredetermined direction up'on;movement of the bracket in a predetermineddi- V rection;

In testimony" whereof affix my signature.
